The evening starts with a guided tour of the palace's art collection, ending at one of its most famous paintings, "The Kiss" by Gustav Klimt.

Afterward, passengers attend a concert in the Marble Hall, an elaborate two-story room with a ceiling fresco painted in 1720 by Carlo Carlone. The concert will feature the music of Johann Strauss (father and son) and Mozart.

The tour continues to the city's historic Ringstrasse, which is where the Austrian Parliament building and Vienna State Opera House are located, before returning to the ship.

Guests will be able to book the free evening event starting in April, when other shore excursions will be announced.
